Junior dos Santos made relatively quick work of Frank Mir in UFC 146 to retain the UFC heavyweight championship and sealed the deal that Mir will never compete for a title again.

In the second round of their fight, dos Santos landed a straight right hand that leveled Mir and sent him rolling backwards. Mir attempted to get up, but fell back having clearly been rocked too hard to come back from.

Cigano dominated most of the fight and never gave Mir a chance to fight in his comfort zone. Instead, dos Santos kept it a boxing match and was simply too much for Mir as evidenced by the second-round finish.

Mir made a few attempts to take this fight to the ground, but all efforts were thwarted by the champ.

The former heavyweight champ has had some great matches throughout his career and many accomplishments to be proud of.

That being said, it doesn't appear that there is much left in the tank for Mir.

Cigano is the class of the division and if Mir wants to return to glory, he'll have to get through that caliber of fighter. However, Mir never stood a chance against dos Santos, further proving he is no longer on an elite level.

So, what's next for Mir?

It's doubtful he'll be dropped off the face of the UFC earth. Mir still has value to the company as a legend, fan favorite and a top-notch measuring stick for new fighters coming into the company.

Although this will be the last you see of Mir in a truly meaningful fight, it won't be the last you see of Mir for good.
